1N4148_S62Z

Single Diodes Overview

The onsemi 1N4148_S62Z is a small signal switching diode belonging to the 1N91x and 1N4x48 family. It utilizes a silicon epitaxial planar structure housed in a DO-204AH (DO-35) axial lead glass package. Key electrical specifications include a maximum repetitive reverse voltage of 100 V, an average rectified forward current of 200 mA, and a DC forward current of 300 mA. The device features a maximum reverse recovery time of 4.0 ns at specified test conditions and a total capacitance of 4.0 pF. Thermal characteristics indicate a power dissipation rating of 500 mW with a junction-to-ambient thermal resistance of 300 °C/W.
